The Epson Powerlite 1715C is a petite unit (3.7 pounds) that comes packed inside its own carrying case along with cables and documentation. Cable operation is a breeze. But wireless connectivity? Not so much. The Epson ships with proprietary wireless software that clashed with my laptop. Once connected, I found that my notebook talked to the projector but could no longer access a Wi-Fi network.
BOTTOM LINE? Use a cable.
